Hi,
i'm playing a bit around with vcpus. My guest is Windows 10 1903. This is the excerpt from the config: ... <vcpu placement='static' current='2'>4</vcpu> <vcpus> <vcpu id='0' enabled='yes' hotpluggable='no'/> <vcpu id='1' enabled='yes' hotpluggable='yes'/> <vcpu id='2' enabled='no' hotpluggable='yes'/> <vcpu id='3' enabled='no' hotpluggable='yes'/> </vcpus> ...
I'm able to hotplug vcpus, but when i want to unplug them i get the following:
virsh # setvcpus pathway 3 --live virsh # setvcpus pathway 4 --live virsh # setvcpus pathway 2 --live error: internal error: unable to execute QEMU command 'device_del': acpi: device unplug request for not supported device type: qemu64-x86_64-cpu
Does anyone know why it can't be unplugged ?
Sounds like qemu doesn't support unplug of vcpus. Which version of qemu do you use?
